Paper Abstract

The distributed strain sensor has significant application in real-time monitoring of the status of large and important engineering structures such as bridges and dams. In this paper, a quasi-distributed optical fiber sensor system is set up using OTDR technique. The strain sensors that base on a novel microbend configuration are designed and used to measure the local strains along the optical fiber. In experimental studies, we are concerned about two questions: the monitoring of the safety status and the strain measurement of the member to be measured. The experimental results are given.
